To all whom it mayconcem: 7

Be it known that we, FRED A. GnrnoLns and EMIL E. MARTINSON, citizens ofthe United States, residing at Globe, in the county of'Gila and State ofArizona, have invented certain new and useful Improvements inHuck-scooping Apparatus; and we do hereby declare the following to be afull, clear, and exact description ofthe invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to muck scooping apparatus and itconsists in thenovel features hereinafter described and claimed.v

An object of the invention is to provide apparatus of simple and durablestructure adapted to be used in mines, stopes and drift shafts forscooping muck and depositing. the same in a car or other receptaclepreparatory to its removal from the mine or shaft.

With this object in view, the apparatus comprises an arch bar adapted tobe placed in the mine or shaft with its legs at the opposite sides of atrack or roadway. A car is adapted to move along the track or roadwayand may be of usual pattern. An I-beam is pivotally connected with theupper intermediate portion of the arch bar and a longitudinallyextensible prop is mounted at the free end of the I-beamand is adaptedto be engaged with the sides of the drift or shaft. A carriage ismounted for movement along the I-beam and is provided with stop deviceswhich may be engaged in notches provided in the beam, whereby thecarriage may be stopped at suitable points along the beam. A block isdetachably mounted in the carriage and a releasing means is providedwhich may be manually manipulated for detaching the block from thecarriage. A scoop is connected with the block. A cable is trained overpulleys mounted upon the carriage and under a pulley mounted upon theblock and is connected with the carriage. The said cable is trainedaround a pulleymounted upon the prop and the end portions of the saidcable are arranged to wind upon drums which are mounted upon avertically dis posed prop positioned in the shaft or drift at one sideof the track or roadway and which carries a suitable engine adapted-tooperate the drums to effect the winding'o'r unwinding of the cable. v i7 1n the accompanying drawings:

.;Fig. 5 is a detail elevation showing the transversely dlsposedlongitudinally exten sible prop at the forward end ofv the beam. Fig. 6is a detail elevation of the upper portion of the arch bar.

. As'illustrated in the accompanying drawings, a track 1 'is positionedupon the floor of the shaftor drift and a car2'is arranged to move alongthe track ina usual manner. The scooping apparatus comprises an arch bar3 provided at its ends with adjustable spikes 4 adapted to be engagedwith the floor of a shaft on drift-at the opposite sides of the track 1whereby the intermediate portion of the arch bar 3 is disposed over thetrack and bridges the same- An Lbeam 5 is pivotally connected at one endwith the upper intermediateportion of-the. arch bar 3 and carrles atits'free end a transversely disposed longitudinally extensible prop 6,

the ends of which may be engaged with the side walls ofthe' shaftordrift. Apulley 7 is mounted upon the intermediate portion of the prop6. The lower flangeof the I-beam. 5 is providedat intervals along itslength withnotches 8. An arm 9is .connected with the lower flangeofthe-I-beam 5 in the vicinity of the archbar 3 andcarrles at its lowerenda pivoted hook 10..the purpose ofwhich will later appear.

A carriage 11 is mounted for movement along the I-beam 5 and is.provided with journaled wheels 12 adaptedto travel-upon the uppersurfaces of the lower flangesof the Lbeam, the saidwheels beingjournaled upon the carriage at the inner surface'sof the sides thereof.A; pulley l3-is journaled upon the carriage 11 at a point below theI-beam. The prop 14, of usualfstructure is adapted to be positioned inan upright posture inthe'mine or drift at one side of the track 3 and anengine 15 is mounted upon the prop 14 Drums- 16 and 17.are journaledupon the prop 1 1: andvare operatively connected w th the englne wherebythe said drums may be rotated by the englne when the same is inoperation. A cable 18 is arranged with its opposite ends connectedWiththe drums 16 and 1? and this able is adapted to be wound uponfirstone of these drums and then the other during operation of the apparatus,as will be later clearly understood. The cable '13 is trained overpulleys 19 mounted uponthe intermediate portion of the arch bar 3 andone run of r the cable 18 istrained over the pulley 13 mounted upon thecarriage 1.1 and passes through the carriage 11. and is sewn-ed to thesame at the point 20. From the point 21. on the carriage 11, the cableis extended and trained over the pulley 7 and is then extended back overone ot'the pulleys '19 and led to the drum 1?. q a

A block 21 is adapted to be received, in the carriage 11 between thesides thereof and the said block is provided with a journaled pulley22'under which the cable 18 a passes. The block 21 is provided at itssides with vertically disposed cleats 23which are approximatelywedge-shaped in side elevation. Stop members 24 are pivotally mountedupon the sides of the carriage 11 andare held toward the same bymeans ofsprings The free end portions of the blocks 24 pass through openings 26provided in the sides of the carriage and. under the influence ofthesprings the inner portions of the blocks may enter the notches 8 uponthe I-beam 5 whereby the carriage may be stopped in its movement uponthe I-beam and when the stops engage in the notches.

When the block 21 is in position between the side walls of the carriage11, the outer surfaces of the cleats 23engage the inner surfaces of thestops and force them outwardly against the tension of the springs 25,Wherebythe inner portions ofthe stops are held beyondathe outer edges ofthe lowerfianges of the I-beam 5.

Levers 30 are fulcrumed at the sides of the carriage 11 and: areprovided at their inner sides with blocks 31 which pass through thesides of the carriage 11 and which are adapted to extend under the lowerends of the cleats 23 when the block 21 is in position in thecarriage11. Springs 32' are connected with the free end portionsof the levers3() and with a cam 34 and are under tenslon with a tendencyto hold theblocks 31 under the lower ends of the cleats 23; The cam 3e is pivoteduponthe carriage 11 and its cam surface is in engagement with the freeends of the levers 30. The cam member 34 is provided with an arm 35 towhich a cable 36 isattachedand the said cable 36 carries a handle grip37. A bail 38 is pivotally connected with the lower portion of the block2l and a scoop 38 is carried by the bail 38. The scoop 39 is provided atits rear end with an eye 41 with which may be engaged thehook 10 carriedby the arm 9, V

(previously mentioned) The operation of the muck scooping apparatus isas follows :The car 1 is moved to a point on the track betweenthe archbar 3 and the pileof muck which is to be removed from the stops orshaft. The engine 15 is then operated sothat the cable 18 is unwoundfrom the drum16 and wound upon the drum 17, therefore the carriage 11 ismoved along the I-beam 5 until the carria e and the scoop are above thepile of none I.

The operator then pulls upon the cable 36 7 whereby the cam member 34:is turned and the free ends of the levers 30 are swung held at a fixedposition upon the I-beam.

a When the scoop 39 has been loweredin contact with the pile of muck, anoperator uses the handles 40 and projects the scoop under the muck. Theengine 15 is then opera tively connected with the'drum 16 whereby thecable 18 is wound upon. the drum 16. This willlli-ftthe block 21 and theloaded scoop 39 and when the lower ends of the cleats23 pass above theupper edges of the levers 30, the said levers are swung under the lowerends of the cleats whereby the block 21. is supported in thecarriage 11.At the same time, the outer surfaces of the cleats 23 comein contactwith the inner surfaces of the stop members 2st and force the said stopmembers out of the notches 18 with which they have been engaged.Therefore, the carriage is released upon the I-beam 5 and as the cable18 continues to be wound upon the drum 16 and unwound from the drum'17the carriage 1.1 is moved toward the arch bar 3 and when the scoop 39arrives in the vicinity of the arm 9, the hook 10 is engaged intheopening 41 and at the same time the operator pulls upon the cable 36which disconnects the block from the carriage as hereinbefore described,and the cable 18 unwound'from the drum 16, thereby permitting' theforward portion of the scoop'to swing downwardly whereby the contents ofthe scoop may gravitate from the same'ancb fall intothe car 2; Thisop-.erationina'y be repeated until the car is loaded when itmayfbe removedfrom the shaft or drift along the roadway or track 1 a in the usualmanner. a

raising and lowering the block and means for detachably connecting thescoop with the beam.
